\\<hexl-mode-map>
A major mode for editting binary files in hex dump format.

This function automatically converts a buffer into the hexl format
using the function `hexlify-buffer'.

Each line in the buffer has an `address' (displayed in hexadecimal)
representing the offset into the file that the characters on this line
are at and 16 characters from the file (displayed as hexadecimal
values grouped every 16 bits) and as their ASCII values.

If any of the characters (displayed as ASCII characters) are
unprintable (control or meta characters) they will be replaced as
periods.

If hexl-mode is invoked with an argument the buffer is assumed to be
in hexl-format.

A sample format:

Movement is as simple as movement in a normal emacs text buffer.  Most
cursor movement bindings are the same (ie. Use \\[hexl-backward-char], \\[hexl-forward-char], \\[hexl-next-line], and \\[hexl-previous-line]
to move the cursor left, right, down, and up).

Advanced cursor movement commands (ala \\[hexl-beginning-of-line], \\[hexl-end-of-line], \\[hexl-beginning-of-buffer], and \\[hexl-end-of-buffer]) are
also supported.

There are several ways to change text in hexl mode:

ASCII characters (character between space (0x20) and tilde (0x7E)) are
bound to self-insert so you can simply type the character and it will
insert itself (actually overstrike) into the buffer.

\\[hexl-quoted-insert] followed by another keystroke allows you to insert the key even if
it isn't bound to self-insert.  An octal number can be supplied in place
of another key to insert the octal number's ASCII representation.

\\[hexl-insert-hex-char] will insert a given hexadecimal value (if it is between 0 and 0xFF)
into the buffer at the current point.

\\[hexl-insert-octal-char] will insert a given octal value (if it is between 0 and 0377)
into the buffer at the current point.

\\[hexl-insert-decimal-char] will insert a given decimal value (if it is between 0 and 255)
into the buffer at the current point.

\\[hexl-save-buffer] will save the buffer in is binary format.

\\[hexl-mode-exit] will exit hexl-mode.

Note: \\[write-file] will write the file out in HEXL FORMAT.

You can use \\[hexl-find-file] to visit a file in hexl-mode.

\\[describe-bindings] for advanced commands." "p"])
